4 Claims.

This invention relates generally to radiators and more particularly tothe cabinet type, in which the heating units are concealed from view byan enclosing casing.

The object of the invention is to produce a highly eficient radiatorthat is readily adaptable to meet all ordinary installation and otherrequirements, prominent among which may. be mentioned first, thelimitation of overall dimeniU sionsto the iiooror wall space availablefor the installation; second, the positioning of the radiator asrequired, for effective and emcient operation, in any designatedlocation in a room; third, the concealment of the radiator from view bygiving it an outward appearance that harmonizes with the surroundingpanorama and avoids undue prominence in the room in which the radiatoris installed; fourth, theavoidance of thedisadvantages of rights andlefts" by the use of inter- ZG changeable and reversible parts andfifth, the reduction in cost of manufacture by producing suchinterchangeable and reversible part from a minimum number of patterns.

Other objects, not specially mentioned above,

' will appear from the detail description of the invention that follows:

A construction suitable for carrying the invention into efiect, isillustrated in the accompanying drawings but I do not wish to beunderstood to as intending to limit myself to the exact form or detailsshown, as various changes may be made therein without departing from thescope of the invention as outlined in the appended claims.

' Fig. 10 is a perspective view of a m'odifled form of front casingmember showing the same provided with upper and lower openings forgrills.

Fig. 11 is a detail sectional view showing the 65 damper and itsoperating means.

' Fig. 5, and

.is made up in the usual manner of two end sec- 30 tions i, i, and anumber of intermediate sections 85, secured in assembled relation byupper and lower tie-rods 2'2, 22a. Nuts 23, threaded on the ends of therods, seat in depressions 24, formed in 5 the outer faces of the endsections.

Each and section is a single casting, chambere at 9, throughout thelower portion thereof intermediate its ends, as shown in Figs. 3 and 4,the chamber extending from about the midpoint of the length of thesection downward, to near the floor level 01' bottom of the radiator,where a threaded opening 32 is provided for a steam or water valve 25 orreturn connection. Above the opening 52, upper and lower nipple openingsit, ii], are provided for connecting an intermediate section 55, 2 withthe end section chamber. 0n the inner side of the chambered portion ofthe end section, fins or ribs 8 are formed and combine with similar finsor ribs it of the adjoining intermediate section to provide verticalpassage for the upward flow of air between the heating units.

Side flanges i, i, formed on the end section are thickened at suitablyspaced points and drilled or cored to provide sockets t, to receivedowels, studs or pins t5 and t-Sa of the casing members, as hereinafterdescribed. The top flange ta of the end section is shouldered at 2, andhas turned-down ends 3, to conform to the inner cross sectional form ofthe top or stool member 2'? of the casing, which is snugly fitted to thesame, in telescoping relation, as best shown in Fig. 14. Front and backopenings I3 are provided for an air valve or a hot water relief valveindicated at 32, in Figs.

3 and 5, such openings leading into the chambered portion of the endsection. A screw plug is used as a temporary closure for one of theopenings. The upper and lower openings 5 and ll,indicated in Figs. 1 and14, are for the passage of the tie rods 22, 22a, above referred to.

The above described end sections are symmetrically formed throughout.for interchangeable use at either end of the radiator, which avoids-thev disadvantages of the so-ca1led"rights and lefts commonly employed inthe art.

The intermediate radiator sections l5 (Figs. 2

hit

to 4 inclusive) are exact duplicates of each other and a description ofone will serve for all of them. As shown in Fig. 4, the intermediatesections are chambered at it, in, parallel relation with the chambers ofthe end sections, and exteriorly, the chambered portion is provided onopposite sides with a fin or rib formation to, substantially the same asthat of the end sections, opposing ribs of adjoining sections combiningto form vertical passages for the upward flow of air between the heatingunits. In addition to the fln or rib formation on the sides, theintermediate sections are provided with ribs id, id, at opposite ends,against which the front and back casing members rest, forming additionalvertical channels for the upward passage of air.

Upper and lower openings 23, iii, are provided on both sides of theintermediate sections leading into the chamber is thereei, such openingsbeing in line with the openings it, id, oi the end sec tions, forconnection in the usual manner, by means of double tapered push nipplesit. lion neoted as described, upper and lower horizontally disposedfluid passages are iormw through the assembled sections.

As shown in Figs. 2 and 3, an opening 20 is formed in the intermediatesections in line with openings H, in the end sections, for passage ofthe lower tie-rod 22a.

In Fig. 14, the above described radiator assert bly is shown enclosed bya casing formation that utilizes the end radiator sections as the endsof the casing and combines with such ends, front, back and top stoolmembers 3i, 4d and 2V, to complete the casing.

The members 3i, 4d and 2?, are ordinarily formed of sheet metal butother material may be employed if preferred.

The front and back members have their edges bent up, forming continuousflanges 35 and it around the four sides thereof, and openings 3t and 4dare formed in opposite side flanges, through which slidable pins 45 and45a are projected to engage the sockets 8, of the end sections, withwhich they become aligned when the casing members are placed in positionat the front and back thereof.

The height of the front member is made less than that of the backmember, to leave an open space between the upper edge thereof and thetop casing member 2?, in which a grill 30 is se cured by having the endsof certain of the rods forming the grill enter sockets 6 of the endradiator sections.

As shown in Fig. 14, the member 40 is dimensioned to make a completeclosure extending downward to the floor at the back of the radiator butthe front member 3! terminates above the floor, leaving an opening thefull width of the radiator, for the inflow of air. Both front and backcan terminate above the floor.

In the modification shown in Fig. 10, the member 36 is similarlydimensioned to make a complete closure at the front of the radiator,reaching from the stool or top member 21, to the floor or bottom of theradiator. To provide the required air inlet and outlet, the member hastwo grilled openings 31 and 39 formed therein, one near the top and theother near the bottom.

In Fig. 12 a wall type 01' radiator is shown in which the front and backcasing members extend downward the full length of the radiator, leavingthe bottom open for the inflow of air.

In Fig. 15, the grilled opening with which the damper cooperates, isshown in the top or stool member of the casing, as indicated at 59.

The difierence in size of the front and back members, shown in Figs. 8and 9, and the different spacing of the slide bolts or pins in each,requires a double set of sockets 6, in the side flanges of each endradiator section, in order that the casing members and/or the endradiator sections may be interchangeably used in assembling the parts.

The stool or top member 21 has its longer edges 28 first bent downwardat right angles to the body portion and the downwardly bent edges thenbent inwardly at about their mid point parallel with the body portion,as indicated at 33 forming the member, in effect, into a flat slottedtube, the open ends of which are fitted snugly in telescoped relation onthe shouldered top flanges of the end radiator sections, as previouslystated.

Mounted within the casing, in the rear of the grill Sit, and coveringthe grilled opening, there is a plate damper 55, pivoted on a sectionalrod 55, fitted in sockets 58 of the end radiator sections. The damperplate has its lower edge and ends bent up, forming a flange around thethree sides, as shown in Fig. 14. When free, the damper by its ownweight, assumes a vertical position, closing the rilled opening. Thedamper centrally of its length, is extended upward above its pivot, bymeans of an attached extension plate 3, the

' upper edge 53 of which is bent over at right angles and notched at 5'!to siraddle a screwsbaft 5E. The screw shaft is swiveled in an opera ingin the downwardly bent edge 723, of the stool member 21, and has a nut56 threaded thereon, which engages the bent over edge 53 of theextension plate M. v

A knob to is secured by set screw as on the outer end 4'! oi the screwshaft that projects through an opening in the stool or top member 21. Byrotating the knob, the nut is caused to travel back and forth on theshaft. In its travel to the left, as viewed in Fig. 11, the nut engagingthe bent over edge of the damper extension plate, forces the damper toturn about its pivot, in a counterclockwise direction and move clear ofthe grilled iron; opening, as indicated in dotted lines in the figurereferred to and continued movement will bring the damper upward to ahorizontal position, to completely close the opening between theiii-turned edges of the stool or top member 21, thus providing therequired regulation when the grilled outlet opening is formed in thestool member, as shown in Fig. 15. On reversing rotation of the knob, tomove the nut in the opposite direction, the weight of the damper causesthe turned over edge of the extension plate to continue in engagementand follow the nut as the damper returns to vertical position, .as shownin full lines in Fig. 11. The nut is given an elongated form and as itsupper rounded edge rides in contact with the inner surface of the stoolmember, it is held from rotating, as the screw shaft is turned by theknob. To prevent the nut from being run off the shaft, a cotter pin 52is inserted in an opening near the end of the shaft to serve as apositive stop for the nut.

As the many important advantages of the invention will be apparent fromthe foregoing, it will not be necessary to describe the same at greaterlength.
